TILE GAUGE.

n Applieationled March 30, 1925. Serial No. 19,516.

To all whomit may concern,"

Be it known that I, VILIJIAM HILTON, a 'subject` of theKing of England,residing `at Seattle, county of King, and State of lashington, haveinvented a ynew'and useful 1mprovement in File Gauges; and I do herebydeclaret-hat thefollowing is a full, clear, and @exact specification,suchas will enable others vskilled in the art to which itappertains tomake and use the'same.`

The invention is an'imp'rovement in iiley gauges in that a vmeans isprovided for gripping the sawi e rlhe lnvent-ion 1s animprovement overmy prior Patent No. 1,521,098,`1ssued December 30th, 1924, and also `myprior application which was filed August 6th, 1923, with the SerialNumber'66414. I

l vention will be seenfrom the 4following description taken inconnection with the draw ings` [wherein Figure 1 1s a side elevation.

` Figure 2 1s a kplan View.

Figure 3 is ase'ctional view on line 3-3 y of Figure 1.

Figure l4 is a section similar to that shown l1n Figure 3 showing an`alternate means for clamping a bracketto the block.

Figure 5 is ya :sectional viewshowing a side view of theclamp shown inFigure 4.

ligure 6 isa Vview 'showing the gauge for f holding the saw teeth atregular intervals.

yFigure 7 .is a viewshowing another alternate arrangementfor holding thebracket to the block.

Figure 8 is a view showingA an alternate arrangement vvfor, holding thefile.'

FigureV 9 is a similar view showing an- .other alternate design. Y

Figure 191s a .view showing a clamp of shell with one end wider than theother and one 'side'open The interior is illed with a block, which maybe of wood or any suitable material, which .has a r straight cut ithrough its center as indicated by the lines et which show thepositionoi a rip saw over `which. the block may be placed while ity is beingiled; and diagonal Acuts through it as indicated by the dotted lines 5and 6 through which cross cut saws may bepla'ced while being filed. 'lnthe metallic sides' are slots 7,

which have enlarged openings 8 at their upper ends and beveled surfaces9 at the lower 'edge 'of the openings which should have a slope similarto that of the saw teeth.

Q-The slots 7 are placed at the ends of the cut-s 4, 5 and 6 so that thesaw will pass through them. e y

At the sides of the block are gauges 10 which engage the teethof the sawand hold it while it is being filed. The gauges 10 are `made ofiiatpieces of material with beveled edges 11 and 12 which engagethe sawteeth,

Vand projections V13 and 14 which may be 'bent around a groove 15 in theheadof a screw 16 which may be screwed' into a hole between the enlargedportions 8 of two of the slots 7 so that as they are turned on one sideof the screw they will engage the teeth of the saw that may be placed inthe center slot and when they are turned on the opposite side they willengage a saw placed through one of the diagonal slots.

The bracket 2 may be constructed with flat pieces otmaterial 17 bent asshown in Figure l1 and having openings V18 in enlarged sections`19 atthe endsV by which the bracket may be held to the block. Theends areheldby thumb screws 20 that may be placed through the. openings 18 andscrewed Y into the ends of the block or into nuts, lugs,

or enlarged portions on the insides of the ends as maybe desired. Theupper ends 21 of the flat pieces ofmaterial 17 are provided ill) Ll ilwilli lioles into wliieii n` bnr 22 linvinfil :i guide bnr lf3 niny beplzieed.
